Calculating the integral by just cutting the paper and weighing it is hilariously clever. Bravo
-
From an engineer- weighing the paper of the area below the curve of the graph and then taking into account the per-square weight of the paper is one of the most ingenius methods of doing a definite integral that I have ever seen. The rocket is an extremely cool idea, but I'm almost too distracted by that wonderful old school integration technique to appreciate the rocket.

I haven’t watched Cody in years. The fact that he’s still wearing the chain mail makes me so happy
-
Making a rocket out of spare parts in a cave. Absolute legend.
-
The fact that you weighed the graph instead of doing a ton of math is amazing.
-
The best of OG YouTube. Rusty metal, cracked containers, duct tape all over, dodgy camera work... what more could we want? So happy Cody's still going strong!

I worked in a pesticide research lab in the 70's, and we used the same weigh-the-paper method to calculate the parts-per-million (or billion) of whatever pesticide we were testing for. We had a PDP-11 and a PDP-12 available to us, but weighing the paper was easier, and just as accurate.

It’s been years since I’ve watched Cody‘s lab. Something I used to watch daily and I got immense pleasure out of this. It’s good to see you’re doing well man.
-
Cody still being active makes me so fucking happy. Thankyou for years of great organic content :D
-
my man cody has been through some rough shit and still to this day has never dropped effort or quality in videos, he will always be one of the few old youtube legends
-
I should add, Cody is a bright and intelligent man - being able to muddle these projects together on a budget is inspiring.
-
Although somewhat dangerous in atmosphere, this would be an amazingly good idea for galactic fuel. In the vacuum of space it becomes a very stable and renewable resource that can easily be shaped for various purposes
-
The computer next to Cody whilst he is doing paper based integration is just a paper weight, whilst the paper weight is the computer. Love it
-
That worked way better than I thought it would! I figured you would have melting problems. I wonder if it would be better to inject both the water and the sodium as a liquid. Or you could fiber reinforce the sodium with something like steel wool. In any case I'm interested to see more!
-
So good to see cody back in good spirits. Seems like he got a new helper
-
I LOVE HOW CODY EXPLAINS ALL THE MATHS AND HARD PARTS!! I hate most documentaries on youtube because they completely skip over the important stuff, figuring their target audience is both dumb and lazy. Cody explains it how you can recreate it.
-
weighing the paper was a clever idea, but subtracting the negative piece by using it to tare the scales was a stroke of genius. you truly have the mind of an engineer

Cody, for flying rockets there’s what’s called the Amateur Exception in the FAA regulations and people regularly build large metallic VTVL and ascending liquid (sometimes hybrid) rockets and fly them. At Black Rock in Nevada the airspace is under a quirky uncontrolled category where the paperwork is particularly easy. The folks at Friends of Amateur Rocketry site in California are great supporters and a launch site as well.

Hey that’s me! Thanks for the autograph Cody!!

I'd advise on using a steam injector that uses the chamber pressure to feed water into the reaction chamber. It will be much more scalable then having to force in water using a compressed gas.
